Question

A restaurant uses rectangular napkins where the length, l, is twice as long as the width. The length of the napkin along the diagonal is x. What is x in terms of l? Replace a and b with the correct values.

Answer 1

Sounds like the Pythagorean theorem 💀

Answer 2

\[x^2 = (\frac{1}{2}i)^2+i^2 \]

take the square root of both sides and you will find x in terms of i
